LOCK.

Application led February 21, 1927. Serial No. 169,792.

My invention relates to a lock, particularly though not exclusively, adapted for use on a swinging lid 'on the rear deck of an automobile.

Heretot'ore, in many locks for the purpose indicated it has been possible to so spring the deck lid relatively to that part carrying the strike plate that the latch could be withdrawn from the strike without actually manipulatingthe latch itself. I

It is the general ob]ect of the present 1nvention to rovide a lock of the character indicated a apted to prevent the lock 'from being sprung relatively to the strike plate so as to withdraw the latch therefrom.v

In the drawings which show, for illustrative purposes only, a preferred formof the invention- Fig. 1 is a view in elevation showing a lock applied to the rear deck lid of an automobile;

Fig. 2 is an outer view in elevation of the lock shown in Fig. 1';

Fig. 3 is a view similar to Fig. 2 but having the cover plate removed to show interior construction Fig. 4 is a sectional view taken substantially in the plane of the line 4-4 or' Fig. 3.

In said drawings, 5 indicates the rear deck lid of an automobile, `while 6 represents a portion of the body of the automobile. The lock case 7 in the present showing is secured to the lid 5 by any suitable means such as screws or rivets. An actuator 8 is positioned in the lock case 7, and may be moved into locking position as by means of springs 99. In the particular form shown, I employ a pair of hooks 10-10, which may be pivotally mounted in the lock case on the pivot pin 11. These swinging hooks are actuated by means ot the part 8 through suitable means such as the pin and slot connection indicated at 12-12 betweenv the rear ends of the latches and the locking bolt. A key controlled means such as a cylinder lock 13 is secured to the lock'case. Any suitable form of roll-back14 carried by the plug of the cylinder lock 13 may serve to retract the actuator 8 yand thus free the hooks 10-10. The springs serve to move the actuator so as to cause the hooks 10-10 to be Y swung into locking position.

15 indicates a strike plate. In order to prevent the lid 5 from being sprung outwardly suiiiciently to disengage the hooks y 10-10 from the strike plate l5, I provide a liXed abutment on one of the members, which abutment takes into the other member. In the form shown, the lock casing 7 carries a fixed abutment 16,between the hooks 10-10 which is thereby adapted to extend into the same opening in the strike yplate 15 as the hooks 10-10. The active surface of the abutment 16 preferably extends at about right angles to the latching direction of the latches 10-10 so that when the latches are in latched position as shown in Fig. 1, the lid 5 cannot be sprung outwardly, that is, toward the right, as viewed in Fig. 1, sufficiently far to disengage the latches from the strike plate. The active abutting surface on the fixed abutment 16 may be of arcuate form and preferably extends substantially perpendicularly to a line between the abutment and the hinge joint of the deck lid 5. It will be seen that, when the latches 10-10 are withdrawn to the unlatched position, the deck lid 5 may be opened, the

`fixed abutment 16 then being removed from its seat in the strike plate. y

While a specific form of the invention has been illustrated, I do not wish to be strictly confined to the particular form shown for changes may .be made within the scope of the invention as defined in the lappended claim.

I claim:

In a lock of the character described, a lock case, a strike plate having an opening therein, a fixed abutment on the lock case adapted to project into the opening of the strike plate, a latching hook carried by said lock case and adapted to etlect locking engagement with one side of said opening in said strike plate bv a movement of said Vhook at substantially right angles to said abutment whereby said lock case and strike plate cannot be sprung relatively to each other sufficiently to `withdraw said hook from locking engagement therewith, an actuator for said latching hook, and a key locking means for operating said actuator.
